Parker Solar Probe is the first ever human-kind technology to touch our Sun
NASA’s Parker Solar Probe is the first-ever mission to "touch" the Sun. The spacecraft, about the size of a small car, travels directly through the Sun's atmosphere --ultimately to a distance of bout 4 million miles from the surface. Parker Solar Probe launched aboard a Delta IV-Heavy rocket from Cape Canaveral, Aug. 12, 2018 at 3:31 a.m. EDT.

NASA's Parker Solar Probe is on a mission to "touch the Sun." The spacecraft is flying closer to the Sun’s surface than any spacecraft before it. The mission will revolutionize our understanding of the Sun.
The Parker Probe will fly more than seven times closer to the Sun than any other spacecraft.
Over the course of seven years, the spacecraft will complete 24 orbits around the Sun.
At its closest approach, the spacecraft will come within about 3.9 million miles (6.2 million kilometers) of the Sun.
As NASA’s Parker Solar Probe approaches its 13th perihelion, or close encounter, with the Sun on Sept. 6, it is heading into a much different solar environment than ever before.

As mentioned earlier, the Parker probe will fly near the Sun where no other spacecraft has ever been. The purpose of this mission to study the nature of the Sun and how it influence the very nature of space. By studying this system, it can help us unlock the mysteries of the Sun and unravel the inner workings of the universe.
Parker Solar Probe will employ a combination of in-place and remote measurements to achieve the mission's primary scientific goals: determine the structure and dynamics of the magnetic fields at the sources of solar wind; trace the flow of energy that heats the corona and accelerates the solar wind; determine what mechanisms accelerate and transport energetic particles; and explore dusty plasma near the Sun and its influence on solar wind and energetic particle formation.
In September 2010, NASA selected five investigations for Parker Solar Probe:
Solar Wind Electrons Alphas and Protons Investigation, which will specifically count the most abundant particles in the solar wind — electrons, protons and helium ions — and measure their properties. The investigation also is designed to catch some of the particles in a special cup (known as a Faraday cup) for direct analysis. Principal Investigator: Justin C. Kasper, Smithsonian Astrophysical Observatory, Cambridge, Mass.; University of Michigan
The Wide-field Imager, a telescope that will make 3-D images of the sun's corona, or atmosphere. The experiment actually will see the solar wind and provide 3-D images of clouds and shocks as they approach and pass the spacecraft. This investigation complements instruments on the spacecraft providing direct measurements by imaging the plasma the other instruments sample. Principal Investigator: Russell Howard, Naval Research Laboratory, Washington
The Fields Experiment, which will make direct measurements of electric and magnetic fields, radio emissions, and shock waves that course through the Sun's atmospheric plasma. The experiment also serves as a giant dust detector, registering voltage signatures when specks of space dust hit the spacecraft's antenna. Principal Investigator: Stuart Bale, University of California Space Sciences Laboratory, Berkeley, Calif.
The Integrated Science Investigation of the Sun, which consists of two instruments that will take an inventory of elements in the Sun's atmosphere using a mass spectrometer to weigh and sort ions in the vicinity of the spacecraft. Principal Investigator: David McComas, Princeton University, Princeton, NJ.
